[0002] Grain inspection refers to the process of testing and evaluating the quality, safety, nutritional components, and related indicators of grains. Its main purpose is to ensure that grains meet national or international standards, protect consumer health and safety, and provide a scientific basis for grain storage, processing, distribution, and trade. Grain inspection also includes physical testing, which mainly tests the grain's moisture content, impurity ratio, grain size, and other physical characteristics. Before testing, impurities must be separated from pure grains to avoid affecting the test results and to ensure the quality and hygiene safety of the grains.

[0003] The existing method for separating corn impurities involves spreading the corn evenly on a platform and manually screening it to separate the impurities. This method requires a lot of manpower, is not only inefficient but also involves a large workload. Utility Model Content

[0005] To achieve the above objectives, this application provides an impurity separation device for grain inspection. The device includes a housing, a filter plate, a manifold plate, and an air supply assembly. The housing has a top plate and a bottom plate arranged opposite each other in a first direction. The top plate has a feed inlet, and the bottom plate has a discharge outlet. A first slag discharge outlet is also provided on the side wall of the housing. The first direction is the same as the height direction of the housing. The filter plate is disposed between the top and bottom plates and forms an angle with the horizontal plane. The feed inlet is located near the high end of the filter plate. The manifold plate is disposed between the filter plate and the bottom plate and forms an angle with the horizontal plane. A first gap exists between the low end of the manifold plate and the side wall of the housing. The first gap and the discharge outlet are opposite each other in the first direction. The air supply assembly is disposed on the side of the bottom plate facing the top plate and is opposite the first slag discharge outlet in the horizontal direction. The path between the first gap and the discharge outlet intersects the path between the air supply assembly and the first slag discharge outlet.

[0024] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Figure 1 This is a schematic diagram of the overall structure of a grain inspection impurity separation device proposed in an embodiment of this application; Figure 2 for Figure 1 A structural schematic diagram from another perspective of the embodiment; Figure 3 This is a schematic diagram of the internal structure of the box according to an embodiment of this application.

[0026] refer to Figures 1-3This application provides an impurity separation device for grain inspection. The device may include a housing 1, a filter plate 2, a manifold plate 3, and an air supply assembly 4. The housing 1 has a top plate 11 and a bottom plate 12 arranged opposite each other in a first direction. The top plate 11 has a feed inlet 111, and the bottom plate 12 has a discharge outlet 121. A first slag discharge outlet 131 is also provided on the side wall of the housing 1. The first direction is the same as the height direction of the housing 1. The filter plate 2 is disposed between the top plate 11 and the bottom plate 12 and forms an angle with the horizontal plane. The feed inlet 111 is located near the high end of the filter plate 2; the manifold 3 is disposed between the filter plate 2 and the bottom plate 12 and has an angle with the horizontal plane, and there is a first gap between the low end of the manifold 3 and the side wall of the housing 1, wherein the first gap is opposite to the discharge port 121 in a first direction; the air supply assembly 4 is disposed on the side of the bottom plate 12 facing the top plate 11 and is opposite to the first slag discharge port 131 in the horizontal direction, wherein the path between the first gap and the discharge port 121 and the path between the air supply assembly 4 and the first slag discharge port 131 intersect.

[0027] The impurity separation device for grain inspection proposed in this application embodiment has the height direction of the box 1 in the same direction as the direction of gravity, and the bottom plate 12 located below the top plate 11. Corn kernels containing a lot of impurities are added into the box 1 through the feed port 111. The corn kernels fall onto the inclined filter plate 2 and roll or slide. The corn kernels pass through the filter plate 2, and larger corn cobs and other impurities are intercepted by the filter plate 2. The corn kernels that pass through the filter plate 2 fall onto the confluence plate 3 and roll or slide to the first gap and fall down. The air supply component 4 blows other impurities in the corn kernels to the first slag discharge port 131. The corn kernels fall to the discharge port 121 and are discharged from the box 1. In this way, corn kernels and impurities can be separated quickly and can work continuously with high separation efficiency, which is convenient for subsequent grain inspection.

[0028] It should be noted that, as Figure 1 As shown, the first direction is the X direction, and the height direction of box 1 is the same as the direction of gravity.

[0029] It should be understood that, as Figure 3 As shown, the filter plate 2 has an angle with the horizontal plane, that is, the filter plate 2 is set at an angle. Therefore, one end of the filter plate 2 is higher and is called the high end, and the other end is lower and is called the low end. The same applies to the manifold 3.

[0030] The feed inlet 111 is located near the high end of the filter plate 2, so that the corn kernels and impurities entering the box 1 from the feed inlet 111 will fall onto the filter plate 2 and be filtered by rolling or sliding along the inclined filter plate 2.

[0031] In addition, the first gap and the discharge port 121 are opposite each other in the first direction, so that when the corn kernels fall out of the first gap, they can fall out of the box 1 through the discharge port 121.

[0032] Furthermore, the size of the discharge port 121 should be larger than the size of the first gap so that the corn kernels can fall out of the discharge port 121.

[0033] It should be understood that the path between the first gap and the discharge port 121 refers to the path of the corn kernels falling, that is, the path that the corn kernels take from the first gap to the discharge port 121; the path between the air supply component 4 and the first slag discharge port 131 refers to the path of the airflow blown by the air supply component 4, that is, the path of the airflow blown by the air supply component 4 to the first slag discharge port 131. When the path between the first gap and the discharge port 121 and the path between the air supply component 4 and the first slag discharge port 131 intersect, the air supply component 4 can blow impurities into the first slag discharge port 131 during the falling of the corn kernels.

[0034] It should be noted that corn kernels are relatively heavy, while impurities are generally lighter. Therefore, the air supply structure can blow most of the impurities other than corn kernels into the first slag discharge port 131, and the corn kernels will fall naturally into the discharge port 121.

[0035] Furthermore, the housing 1 has a left side plate 13 and a right side plate 14 facing each other in a second direction, the second direction being the same as the length direction of the housing 1; wherein, the first slag discharge port 131 is disposed on the left side plate 13, a first gap is formed between the confluence plate 3 and the left side plate 13, and the air supply assembly 4 is facing the first slag discharge port 131 in the second direction.

[0036] Among them, such as Figure 1 As shown, the second direction is the Y direction.

[0037] refer to Figure 3 In an exemplary embodiment, the lower end of the filter plate 2 is close to the right side plate 14, and the right side plate 14 is provided with a second slag discharge port 141, which is located at the lower end of the filter plate 2.

[0038] Specifically, the second slag discharge port 141 is located at the lower end of the filter plate 2, so that larger impurities such as corn cobs that roll off the filter plate 2 can be discharged from the housing 1 through the second slag discharge port 141.

[0039] refer to Figure 3 In an exemplary embodiment, the impurity separation device for grain inspection may further include a second slag discharge pipe 5, which is located outside the housing 1 and connected to a second slag discharge port 141; wherein, in the first direction, the second slag discharge pipe 5 gradually approaches the bottom plate 12 in a direction away from the second slag discharge port 141.

[0040] Specifically, the end of the second slag discharge pipe 5 away from the box body 1 extends downward at an angle so that a woven bag or other container for collection can be connected at the second slag discharge pipe 5 to collect large pieces of corn cobs and other impurities.

[0041] refer to Figure 3 In an exemplary embodiment, the lower end of the filter plate 2 is close to the right side plate 14 and has a second gap with the right side plate 14.

[0042] Specifically, such as Figure 3 As shown, there is a gap between the filter plate 2 and the right side plate 14. When the corn kernels move on the filter plate 2, if they fail to fall through the holes of the filter plate 2, they can eventually reach the gap between the filter plate 2 and the right side plate 14 and fall onto the confluence plate 3, thus preventing the corn kernels from accumulating on the filter plate 2.

[0043] Furthermore, the impurity separation device for grain inspection may also include a plate vibrator. The plate vibrator is installed on the side of the filter plate 2 facing the confluence plate 3. The filter plate 2 can be made of plastic with a certain deformation capacity. After the plate vibrator is installed, the plate vibrator will drive the filter plate 2 to vibrate, thereby making it easier for the corn kernels on the filter plate 2 to move on the filter plate 2, effectively preventing the corn kernels from accumulating on the filter plate 2.

[0044] refer to Figure 3 In an exemplary embodiment, the air supply assembly 4 may include a mounting base 41 and a fan 42, wherein the mounting base 41 is fixed to the base plate 12 and the fan 42 is fixed to the mounting base 41.

[0045] Specifically, the airflow blown by the blower 42 reaches the first slag discharge port 131, so that the blower 42 can blow the impurities in the corn kernels out of the first slag discharge port 131.

[0046] refer to Figure 1 and Figure 3 In an exemplary embodiment, the housing 1 further includes a back panel 15 and a door 16 disposed opposite each other in a third direction, the third direction being the same as the width direction of the housing 1; wherein, an air inlet 151 is provided on the back panel 15.

[0047] Among them, such as Figure 3 The image shows the state of the box body 1 after removing the door 16. The door 16 is hinged to the main body of the box body 1. Opening the door 16 allows for convenient and quick maintenance, replacement, and cleaning of the internal structure of the box body 1.

[0048] In addition, the air inlet 151 on the back panel 15 can ensure the airflow of the fan 42.

[0049] In an exemplary embodiment, the impurity separation device for grain inspection may further include a plurality of support legs 7, which are disposed on the side of the base plate 12 away from the top plate 11.

[0050] In this embodiment, there are four support legs 7 distributed at the four corners of the base plate 12. In this way, the support legs 7 can support the box 1 to a certain height, making it easier to place a collection container under the base plate 12 to collect the corn kernels after removing impurities, making it more convenient to use.

[0051] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
